Across
- 3. disease that is caused by the invasion of a host by a pathogen and can be transmitted to other individuals.
- 7. A living intermediary that carries an agent from a reservoir to a susceptible host. Examples of vectors include mosquitoes, fleas, or ticks.
- 9. The transfer of an agent from a reservoir to a host either by being suspended in air particles (airborne), carried by an inanimate objects (vehicleborne), or carried by an animate intermediary (vectorborne).
- 10. A disorder of structure or function, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury.
- 11. disease A zoonotic disease is a disease that can be spread between animals and humans.
- 14. Any disease-causing agent.
- 16. The occurrence of more cases of disease, injury, or other health condition than expected in a given area or among a specific group of persons during a particular period. Usually, the cases are presumed to have a common cause or to be related to one another in some way.
- 17. Any mode or mechanism by which an infectious agent is spread to a susceptible host.
Down
- 1. Immediate transfer of an agent from a reservoir to a host by direct contact or droplet spread.
- 2. A living organism that is susceptible to or harbors an infectious agent under natural conditions.
- 4. The amount or number of occurrences of an attribute or health outcome among a population. The resulting rate allows epidemiologists to compare disease occurrence across different populations.
- 5. An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
- 6. An inanimate object that can be the vehicle for transmission of an infectious agent (e.g., bedding, towels, or surgical instruments).
- 8. The study of the distribution and determinants of health conditions or events among populations and the application of that study to control health problems.
- 12. It is the occurrence of more cases of disease, injury, or other health condition than expected in a given area or among a specific group of persons during a specific period. Usually, the cases are presumed to have a common cause or to be related to one another in some way. Sometimes distinguished from an epidemic as more localized, or the term less likely to evoke public panic
- 13. An epidemic occurring over a widespread area (multiple countries or continents) and usually affecting a substantial proportion of the population.
- 15. This occurs when a health department is proactive and contacts health care providers or laboratories requesting information about diseases.
